Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986880, here are decompositions:

17 + 4294986863 = 4294986880
29 + 4294986851 = 4294986880
113 + 4294986767 = 4294986880
179 + 4294986701 = 4294986880
251 + 4294986629 = 4294986880
383 + 4294986497 = 4294986880
389 + 4294986491 = 4294986880
491 + 4294986389 = 4294986880

Showing the first eight; more decompositions exist.
